I Think im not the only one with this problem.
I just bought my first Elogger V4 from HobbyWireless but until now i couldn't make it works. All i got is a blinking LED. ***********
When I connect to my laptop I got the "Unknown Device" .I tried with 4 differents Desktops and 3 laptops (Sony,Acer and Dell) and got the same problem.
I also tried with a powered USB HUB, with and without battery connected.
Im from Brazil and it tooks almost 2 months to arrive, so I hope there are others suggestion to solve my problem.
